GRANULATING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 260,123, dated June27,1882.

Application filed December 30, 1881. Y(No model.)

To all whom it may concern Be it known that we, JACOB READ, of Yonkers,in the county of Westchester and State of New York, and SAMUEL G.BURDICK, of the city of Orange, county of Essex, and State ot' NewJersey, have invented a certain new and useful Machine for Granulatin gGlucose Cake; andwe do hereby declare that the following specification,taken in connection with the drawings furnished and forming a partthereof, is a clear, true, and complete description of our invention.

Our machines embody, as anovel and characteristic feature, a gan got'splitting or rip saws, the teeth of which, in the performance of theirgranulatingservice, travel in various lines, or, in other words,pass incontact with the glucose cake, so that the teeth of each saw will notonly Voperate. in a space equal to the thickness of the saw, includingits set,77 but also overlap on each side, so as to include space notcovered by the teeth of the saws next adjacent.v This` peculiaroperation is rendered important ou 'account'of the tenacious characterof the cake.

A gang of ripping gig-saws may be relied upon for fair performance, ifthe saws be inclined laterally, or, if not inclined, they may beoperated with a complex longitudinal and lateral movement; but we prefera gang of circularsplittingorrip saws angularly mounted upon an arbor,so that each wil-l operate as. what are termed wabbling or drunken saws.With these saws means of rvarious kin'ds may be employed for aiding inthe proper presentation and feeding of the cake thereto.

YThe gig-saws referred to would perform fair service, and although thecircular form is much more desirable, we do not limit ourselves thereto,except as hereinafterindicated.

After a detailed description of a machine embodyingour invention, andcertain suggestions as to such variations as may be made therein, ifdesired, the features deemed novel will be specified in the severalclaims hereunto annexed.

Referring to the two sheets of drawings, Figure 1, Sheet 1, is a planview ot' one of our machines as preferred by us. Fig. 2 is alongitudinal vertical section of the same mainly on a central line, butpartially on a line with the center of one side of the frame of themachine. Fig. 3 is a lateral vertical section of the same on line x,Figs. 1 and 2.

'The frame A may be constructed of any suitable material and in anydesired form consistent with the purposes intended, provision being dulymade for properly mounting the moving parts thereon.

The saw-arbor B is mounted in suitable boxes and provided with adriving-pulley. Inside of its boxes there is, at each end, afirmlymounted collar, a, one ot' which is engaged by a clamping nut, b,fitted to a threaded portion, b', of the arbor, as seen in Fig. 1. Eachcollar a has a pair ot' lateral adjusting-screws, c, which are providedwith set-nuts c', for angularly adjusting the saws d with relation totheir arbor.

- .Between the saws there arex annular disks lbut a wider range ofmovement can be einployed.

' rEhe inner ends of the screws c may be provided with recessed seats inthe sides ot' the outer clamping-disks, c, and thereby assure theirrotative connection with the arbor. The

lteeth ofthe saws are of the splitting or ripping order, and may be usedwith or without any set thereto. This gang of wabbling saws will performthe service desired, however the cake may be presented thereto, providedsaid cake is maintained practically stationary as against Athe tendencyof the saws to move it. So far as our knowledge extends, neither agangofwabblingrip-saws nor ripping gig-saws,

,as before herein referred to, have before been employed for any similarpurpose, and such ripsaws, in combination with means of any kind forconfining the cake against the moving action of the, saws and enablingsaid cake to be v progressively delivered thereto for granula- IOO tion,constitutes the main feature of our invention. The simplest embodimentof this combination would be the gang of ripsaws and a table arrangedwith relation thereto, after the manner of an ordinary saw-table. It is,however, preferable that the cake be presented to the saws more nearlyin the plane of their arbor than would be the case as above indicated,and the dangers attendant upon feeding the cake by hand renderitimportant that the machine be organized with special reference toautomatically performing the service intended in the best manner.The-action of the saw teeth also renders it desirable that the cake beconfined against lateral movement, and in view of these severalconditions we have devised a feeding-table well suited for our purposes.

In front of the saws, and below the plane of their arbor, is asupporting-bed, C, upon which the front end of the glucose cake D restsclosely adjacent to the saws. A table, f, is horizontally supported in aplane slightly below the top of the supporting-bed. Said table serves asa support for the series of endless belts g, drivenvby means of belt andgearing, connected with the drum-shaft h near the saws. At the front ofthe machine the endless-belt pulleys are mounted on a shaft, t', havingits bearings in the upper end of a frame pivoted at its foot, and havingset-screws 7c, by which said endless belts may be readily tightened. Thespeed of the endless belts lnay be varied, if desired, by means of thecone belt-pulley shown.

At each side of the table is a side plate, Z, the distance between thetwo being equal to the width of glucose cakes as usually produced. Theoperation of the machine thus described is obvious, it being readilyseen that the cake, being deposited upon the belts, will be slowly fedto the saws, and that the cake will meantime be suiiciently confinedagainst the moving effect of the saws. When one cake is nearly worked upa succeeding cake causes Vthe remains of the first to be advanced to thesaws until wholly granulated.

It is obvious that for obtaining uniform results in granulation thefeeding of the cake should be as uniform as possible. Vhen a large heavycake is put upon the endless belts and presented to the saws itsgradually-diminishing weight will cause a gradual decrease in thefrictional contact between it and the bel ts,

which can be compensated for by increasing the speed of the belts, aswith the cone-pulley. It can also be provided for by having the tablefpivoted to the drum-shaft h and securing to the opposite end of saidtable the pivoted frame in which the front drum-shaft, e', is mounted,and providing a screw or lever by which the front end of the table maybe raised or lowered for varying its inclination, and thus enabling thebelts to maintain a practically uniform control of the cake regardlessof its decreasing weight. The table being thus pivoted, thesupportingbed C should be connected therewith so that its upper surfacewould always occupy the same plane as the belts. The grad uations infeeding afforded by the cone-pulley are generally suiiicient for allpractical purposes.

Considerable uniformity in feeding may be obtained without anygraduating mechanism by careful attention in keeping on the bedsuccessive cakes of glucose of an aggregate weight as uniform aspossible; but this would generally necessitate, as a preliminarymeasure, the transverse sawing of the cakes into short and comparativelyuniform lengths.

We are aware that spiraled plates with crossA cut teeth have heretoforebeen employed in mai chines for making wood pulp; but such plates areunsuited for our purpose, unless provided with splitting7 or rippingteeth, because the cross-cut7 teeth, iu operation upon glucose cake,have insucient capacity for clearance, and are speedily lled withglucose, and therefore fail to produce the granulating effect de sired.i

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. The combination, substantially ashereinbel'ore described, of .a gang of granulating- 95 saws havingsplitting or ripping teeth and a bed for supporting the material to begranulated while presenting it to the saws.

2. The combination', substantially as bereid before described, of a gangof wabbling circular ripping-saws and a bed for supporting the materialto be granulated while presenting it to the saws.

3. The combination, substantially as herein before described, of a gangof wabbling rip pingsaws and a bed provided with feeding mechanism forprogressively presenting to the saws the material to be granulated.

4. The combination, substantially as hereinbefore described, of a gangof wabbling ripping-saws and a bed provided with variablyoperatedfeeding mechanism, whereby the solid mass of material to be granulatedmay be fed to the saws with practical uniformity, regardless of itsprogressively-diminished weight.

5. The combination, substantially as hereinbefore described, ot' a gangof wabbling ripping-saws and a bed provided with side plates forlaterally contning the mass of material to be granulated in presentingthe same to the saws.

6. The combination of thearbor and the gang of wabbling circularripping-saws simultaneously adjustable to any desired inclination onsaid arbor, substantially as described.
